Gaskins says that he thought of "PowerPoint", based on the product's goal of "empowering" individual presenters, and sent that name to the lawyers for clearance, while all the documentation was hastily revised.
The Excel formats can be used without ever opening Excel, gorgeous. Can you please explain? PropertiesProperty you see the two dots? Property to a variable and use and dispose that variable. A more formal version of the above rule could be sth. This includes com objects that are properties of another com object.
Actually, you don't need any kind of cleanup, since the garbage collector will do it for you. The only thing you need to do is to assign every COM object to its own variable so the GC knows of it. It just might take forever for the GC to clean it up. Collect after heavy interop isn't a bad idear.
The advice to maintain a named reference for absolutely every COM object you access and then explicitly release it via Marshal.
FinalReleaseComObject is correct in theory, but, unfortunately, very difficult to manage in practice. If one ever slips anywhere and uses "two dots", or iterates cells via a for each loop, or any other similar kind of command, then you'll have unreferenced COM objects and risk a hang.
In this case, there would be no way to find the cause in the code; you would have to review all your code by eye and hopefully find the cause, a task that could be nearly impossible for a large project.
The good news is that you do not actually have to maintain a named variable reference to every COM object you use. Collect and then GC.
WaitForPendingFinalizers to release all the usually minor objects to which you do not hold a reference, and then explicitly release the objects to which you do hold a named variable reference. You should also release your named references in reverse order of importance: For example, assuming that you had a Range object variable named xlRng, a Worksheet variable named xlSheet, a Workbook variable named xlBook and an Excel Application variable named xlApp, then your cleanup code could look something like the following: WaitForPendingFinalizers ; This should not be required, however, unless you are using Visual Studio Tools for Office VSTOwhich uses finalizers that cause an entire graph of objects to be promoted in the finalization queue.
Such objects would not be released until the next garbage collection. I know that explicitly calling GC. Collect is a no-no and certainly doing it twice sounds very painfulbut there is no way around it, to be honest.
Through normal operations you will generate hidden objects to which you hold no reference that you, therefore, cannot release through any other means other than calling GC. This is a complex topic, but this really is all there is to it. Once you establish this template for your cleanup procedure you can code normally, without the need for wrappers, etc.Dotdash's brands help over million users each month find answers, solve problems, and get inspired.
